Two mock-ups of the Hubble Space Telescope used for training simulations at the Johnson Spaceflight Center, Texas. On the left is a full- scale mock-up and on the right a helium-filled balloon of the same size & shape as the telescope. The balloon is used to represent the telescope under weightless conditions during deployment simulations using the shuttle's remote manipulator arm. This image gives a good impression of the size of the Space Telescope; it measures 13.25 metres in length & 4.25 metres in diameter.
